Avoid the use of sodium dodecyl sulphate dentifrice, although this is controversial.

Avoid the use of sodium dodecyl sulphate dentifrice, although this is controversial.

Preferred modifiers include NaOH, urea sodium dodecyl sulfate, sodium dodecylbenzene sulfonate, and guanidine hydrochloride.

Exposure to tert-dodecyl mercaptan may also occur as a result of using some paint and coatings products available to consumers.

The transduction enhancing agent can be a mono-,di-or poly-saccharide having a lipophilic substituent such as n-dodecyl-β-D-maltoside (DDM).

A preferred form of the composition contains lactoperoxidase, monolaurin or sodium dodecyl sulphate, a source of peroxide, and thiocyanate ions.

Some of these substances may be used in certain food packaging materials in Canada; however, exposure from food is negligible.

The surfactant layer (32) is preferably an alkyl dimethylbenzyl quaternary, an alkyl trimethyl quaternary, a dialkyl dimethyl quaternary, sodium lauryl sulfate, or pyridinium chloride.

The invention concerns an immunoglobulin binding, especially IgM binding, protein with an apparent molecular weight of about 160 kD on SDS-PAGE (sodium dodecyl sulphate-poly-acryl-amide gel) and subfragments thereof.

In the method cytokeratins from whole carcinoma cells are purified by preparative SDS-PAGE.

DCPD may be used in the manufacture of food packaging materials in Canada; however, exposure is not expected.

This technique involves two distinct separation methods that have been coupled together: isoelectric focusing (IEF) and sodium dodecyl sulfate polyacrylamide gel electrophoresis (SDS-PAGE).

In one embodiment, the device includes a breast shield modified to engage a non- woven material which has been impregnated with a milk soluble active agent such as sodium dodecyl sulphate (SDS).

The denaturant is preferably an amphiphilic compound, most preferably an anionic amphiphilic compound such as a long chain alkyl sulphate mono ester, preferably an alkaline metal salt, for instance sodium dodecyl sulphate.

A cleaning solution for a storage tank of the present invention comprises: 100 parts by weight of an organic acid; and 1-10 parts by weight of dodecyl glycerol polyethoxylate represented by chemical formula 1.
